Sonoran Turquoise mining is becoming scarce. Some of the mines have already closed.
This is a clear turquoise from Pino Chueco mine in Sonora, Mexico which resembles the deep blues of Sleeping Beauty. It is medium light-blue with
no matrix and a little pyrite. The turquoise is very unique in that it is found as free-form nuggets in clay material, rather than in rock veins. The mine has produced this turquoise, since the mid-1980s. Archaeology also shows that Southwestern peoples mined these deposits extensively. There are also historical traces of Native American turquoise mining.
